v0.65 released

Our next development release v0.65 is out, with a few big changes. First and foremost, this release includes a complete revamp of the architecture for the command line interface in order to lay the groundwork for our ongoing REST management API work. The ‘ceph’ command line tool is now a thin python wrapper around librados. Note that this set of changes includes several small incompatible changes in the interface that tools or scripts utilizing the CLI should be aware of; these are detailed in the complete release notes.

Other notable changes:

mon, ceph: huge revamp of CLI and internal admin API. (Dan Mick)

mon: new capability syntax

osd: do not use fadvise(DONTNEED) on XFS (data corruption on power cycle)

We have one more sprint to go before the Dumpling feature freeze. Big items include monitor performance and stability improvements and multi-site and disaster recovery features for radosgw. Lots of radosgw has already appeard in rgw-next but these changes will not land until v0.67.
